I'll try to get you the VC part number tomorrow (it's at home). I just did the valves on my 4JG2 which I used a 4JB1 gasket for. It's just a rubber 'o-ring' type deal, so you may be able to re-use the original. Mine was pinched/cut, so I was lucky I bought the new one.

In return, could you tell me what PN you used for the rear main seal?

Great choice of motor. You'll be happy with that over the 2.2. The 2.8 will fit in the first gen body better than the 3.1. I had to do some extra work to fit the 3.1 in my first gen.
